Goats are born with teeth which are replaced by permanent teeth as they age.The VTNE sample questions may cover biology, medications, genetics, laboratory equipment, and cell activity. In the back on their mouth they do have both upper and lower teeth. Goats have no upper front teeth (incisors) their upper front mouth is one big gumline. Estrus is the time of "standing heat" when the cow will stand to be mounted by the bull.
Average estrus is 21 days and lasts for 18 to 24 hours, but heat stress can shorten this window. This means that they have estrus cycles year round. In a red bag delivery, the entire fetal-placental unit is being delivered all at once and thus can cut off the oxygen supply to the fetus prior to birth this can result in death of the fetus if parturition is not facilitated immediately.Ĭows have non-seasonal polyestrous cycles. Under normal circumstances, the fetus breaks through the chorioallantois at the cervical star, and the fetus and amniotic sac are delivered first. The chorioallantois interfaces with the mare's endometrium and is the interface that transfers oxygen to the fetus. Red bag is the layman's term for premature separation of the chorioallantois from the placenta and is a medical emergency. When inflating the lungs, the pressure should reach but not exceed 20 cm H2O.

Question 4: In a pregnant mare, "red bag" delivery implies what situation? The pressure on the manometer to which you ventilate the patient is: The doctor instructs you to give the patient a breath. Question 3: A patient under anesthesia is hypoventilating and the end-tidal CO2 is rising.
Question 2: A cigar-shaped mite that is seen on a skin scraping from a dog with severe generalized skin lesions is probably what type of mite?
Question1: Bacteria differ from animal cells in which of the following ways?ĭ) They lack a true membrane-bound nucleus
